Manufacturing method of multipurpose holder using PET {MANUFACTURING METHOD OF MULTIPLE PURPOSE HOLDER USING POLYETHYLENE TEREPHTHALATE}

The present invention relates to a method for manufacturing a multi-purpose holder using a PET, and more particularly, to a multi-purpose holder using a PET to increase surface adhesion between a front face and a rear face by folding a plastic plate made of polyethylene terephthalate. It's about manufacturing methods.

In general, a holder is a tool used as a means for fixing memo papers on which important things to remember in real life are recorded, and is usually conveniently fixed to a wall surface or a desk top.

Regarding such a holder, Korean Patent Registration No. 10-2035965 "Multipurpose board attached to a monitor" consists of overlapping two boards, except for one side that is opened by using the front board as a transparent board, and the other three sides. is bonded with ultrasonic waves to press the edge of the cut surface of the plate material outward and bend it so that the two sheets of plate material are cut and bonded at the same time, and the edge of the cut surface is pressed backward and the double-sided tape is placed on the bent back side. A technology has been disclosed in which the tape is attached to the monitor and prevents the adhesive portion of the double-sided tape from being exposed to the outside.

The above registered patent secures an intervening space by overlapping two plates, and prevents the bonding area from being formed when bonding the remaining sides except for one side that is open, so that the front and back plates are maximized with a minimum area. The width of the space is secured so that it can be used.

However, since the conventional holder is made so that the remaining sides except for one open side are adhered, when inserting a memo pad or document sheet, it is possible only at the position of one open side, so there is a problem in that it is inconvenient to insert the memo pad or document sheet.

In addition, as the remaining sides except for one open side are bonded, a separation space is formed at the center of the front and rear surfaces, so that when a memo pad or sheet of paper is inserted, it flows down the holder.

The present invention was devised in view of the above situation, and an object of the present invention is to form a folding line on one side of a plastic plate made of polyethylene terephthalate, and fold the front and rear surfaces on both sides based on the folding line. It relates to a method of manufacturing a multi-purpose holder using a PET that can easily achieve holding for a holding object by overlapping the front face and rear face to increase surface adhesion.

In order to achieve the above object, the method of manufacturing a multipurpose holder using a PET according to the present invention is to form a folding line 20 from the top to the bottom on one side of a plastic plate 10 made of polyethylene terephthalate having a predetermined area. In the forming folding line processing step (S10), a hot melt adhesive line 50 is placed horizontally with the folding line 20 on one side of the plastic sheet material 10 at a position spaced apart from the folding line 20 by a predetermined distance. In the forming bonding line forming step (S20), fold the front face 30 and the rear face 40 on both sides based on the folding line 20 so that they overlap, but the width of the front face 30 is the rear face In the step of overlapping the facepieces to be relatively shorter than the width of (40) (S30), and pressurizing the area where the hot melt adhesive line 50 is formed, the front face body 30 and the rear face body 40 are hot melt bonded. It may be configured to include a face pressure step (S40) for bonding by the line 50.
As an example, the hot melt adhesive line 50 may be composed of a hot melt adhesive that is melted by applying heat in a solid state without adhesive strength.
In one embodiment, the plastic sheet material 10, preferably has a thickness of 0.2mm ~ 0.5mm.

1 is a development view of a plastic sheet material according to the present invention, Figure 2 is a state diagram in which the front surface body and the rear surface body on both sides of the plastic sheet material according to the present invention are folded and overlapped with respect to the folding line, Figure 3 is a front view according to the present invention A cross-sectional view of the hot melt adhesive line formed between the facepiece and the rear facepiece.

As shown in FIGS. 1 to 3, in the multipurpose holder using the PET according to the present invention, a folding line 20 is processed from the upper side to the lower side on one side of the plastic plate 10 made of polyethylene terephthalate, so that the folding Based on the line 20, the front face 30 and the rear face 40 are folded and overlapped, and the width of the front face 30 is shorter than the width of the rear face 40, and the folding line (20) is configured to be located inside the folding direction of the front face body (30) and the rear face body (40).

In the present invention, a folding line 20 is formed along the longitudinal direction on one side of a plastic plate 10 made of polyethylene terephthalate having a predetermined area, and the front face 30 on both sides based on the folding line 20 When folding and overlapping the rear face body 40, the front face body 30 and the rear face body 40 are not elastically opened due to the folding line 20.

This is a phenomenon in which, when both sides of the plastic sheet material 10 are folded and overlapped in a state in which the folding line 20 is not formed, the folded portion is formed round in cross section, and thus the folded sides are widened based on the folded portion. this will happen Accordingly, in the present invention, the folding line 20 is formed on one side of the plastic plate 10 made of polyethylene terephthalate, and the front face 30 and the rear face 40 on both sides are folded and overlapped based on the fold line. It is to prevent the unfolding of the folded both sides of the front face body 30 and the rear face body 40.

In addition, when the front face body 30 and the rear face body 40 are folded based on the folding line 20, the width of the front face body 30 is smaller than the width of the rear face body 40, so that the front face body 40 A holding object between the face body 30 and the rear face body 40, as an embodiment, it is possible to easily insert notes or documents.

That is, in the case where the front face 30 and the rear face 40 are folded and overlapped by the folding line 20, a sheet of paper or a document is inserted between the front face 30 and the rear face 40, When a memo pad or document sheet is pushed between the front surface body 30 and the rear surface body 40 in a state where it is closely positioned on the exposed surface of the rear surface body 40 exposed on one side of the front surface body 30, the memo paper or Insertion of paper sheets can be done easily.

In addition, surface adhesion between the front face body 30 and the rear face body 40 can be increased by positioning the folding line 20 on the inner side of the front face body 30 and the rear face body 40 in the folding direction. As a result, it is possible to increase the holding force of memo pads or sheets of documents sandwiched between the front face body 30 and the rear face body 40.

Here, the reason why the plastic plate 10 is polyethylene terephthalate (PET) is that it is recyclable and has excellent impact strength compared to PVC or acrylic, so that scratches caused by external factors are reduced. This is because it is possible to prevent deterioration of marketability even if the intestines are stored overlapping, and to prevent warping due to deformation due to heat due to excellent heat resistance, and to prevent cracking in winter.

In addition, the plastic sheet material 10 made of polyethylene terephthalate preferably has a thickness of 0.2 mm to 0.5 mm, which means that when a plastic sheet material having a thickness of less than 0.2 mm is used, the multi-purpose holder is not flexible. Distortion occurs, resulting in a problem in that the surface adhesion between the front face and rear face is lowered, and when using a plastic plate of more than 0.5 mm, the weight of the multi-purpose holder and the manufacturing cost increase. The plate material 10 is preferably to have a thickness of 0.2mm ~ 0.5mm.

When the front face body 30 and the rear face body 40 are overlapped with each other based on the folding line 20, the height of the front face body 30 is relatively greater than the height of the rear face body 40. It is shortened so that the upper and lower sides of one side of the rear face body 40 are partially exposed.

This is, when a memo pad, sheet music, or sheet of a certain area is inserted between the front face 30 and the rear face 40, in a state in which they are in close contact with the upper and lower exposed surfaces of one side of the rear face 40. It can be easily inserted between the front face body 30 and the rear face body 40.

A hot melt bonding line 50 is formed between the front surface body 30 and the rear surface body 40, and the hot melt bonding line 50 is spaced apart from the folding line 20 at a predetermined interval to It is formed to have a uniform width and straightness along the longitudinal direction between the rear face body 40, and the front face body 30 and the rear face body 40 are attached to each other.

The hot melt adhesive line 50 applied with the hot melt adhesive is formed at a position spaced apart from the fold line 20 at a predetermined interval so that the front face body 30 and the rear face body 40 are mutually adhered to each other, so that the front face body 30 ) and the rear face body 40 to have uniform surface adhesion over the entire surface of the front face body 30 and the rear face body 40.

At this time, the hot melt adhesive used in the hot melt adhesive line 50 preferably has an amount of 0.5 g to 1.5 g, which is when the hot melt adhesive is less than 0.5 g, the front face 30 and the rear face 40 If it is not possible to form a uniform amount along the length direction of the hot melt adhesive and the hot melt adhesive exceeds 1.5 g, the thickness of the hot melt adhesive line 50 becomes thick, and the front face body 30 and the rear face body 40 It is preferable that the hot melt adhesive used in the hot melt adhesive line 50 has an amount of 0.5 g to 1.5 g because it reduces surface adhesion.

Here, the hot melt adhesive is described as having an amount of 0.5 g to 1.5 g, but is not limited thereto, and the amount may vary depending on the size of the holder.

The reason why hot melt adhesive is used in the hot melt adhesive line 50 is that the hot melt adhesive is melted by applying heat in a solid state without adhesive strength, so the drying speed is fast and workability and production efficiency can be improved. It is harmless to the human body and has no odor, so it can provide safety to workers during the work process.

In particular, since the product does not melt or deteriorate at high temperatures during product production, when the plastic plate 10 made of polyethylene terephthalate is folded and adhered, while preventing damage to the front face 30 and the rear face 40 It is preferable to use a hot melt adhesive when forming the hot melt adhesive line 50 because a high quality multipurpose holder can be provided and a uniform straightness can be formed due to high adhesive strength.
